Methods and apparatus for SAN having local server storage including SSD block-based storage

A method, comprising:

• coupling a control system to a data system to control a mapping table of an address to a corresponding hash value;
• coupling a routing system to the control system to identify and process a new read command from a remote host by:
• instantiating a first thread that is configured to poll a TCP/IP socket and store any partial data associated with the read command in a buffer until the entire read command is stored into the buffer, and instantiating a second thread that is configured to execute the read command after the entire read command has been stored into the buffer;
• coupling a controller to solid state drive (SSD) storage of a storage array, wherein the controller includes a data system to perform input/output operations to the SSD storage based upon at least one of physical addresses of data blocks and hash values of the data blocks;
• and
• associating a data server with the routing system to receive the read and write commands from a data client running on the remote host,
• wherein the storage array contributes a portion of the SSD storage to storage pools of a distributed elastic storage system,
• wherein at least one logical volume of the storage pools is maintained as private such that the logical volume is available only to a corresponding remote host via a corresponding routing system.

An article, comprising:

• a non-transitory computer readable medium baying stored instructions that enable a machine to:
• control a controller coupled to solid state drive (SSD) storage of a storage array;
• communicate with a control system to control a mapping table of an address to a corresponding hash value;
• communicate with a routing system coupled to the control system to identify a read command from a remote host by:
• instantiating a first thread that is configured to poll a TCP/IP socket and store any partial data associated with the read command in a buffer until the entire read command is stored into the buffer, and instantiating a second thread that is configured to execute the read command after the entire read command has been stored into the buffer;
• control a controller coupled to solid state drive (SSD) storage of a storage array, wherein the controller includes a data system to perform input/output operations to the SSD storage based upon at least one of physical addresses of data blocks and hash values of the data blocks;

• wherein the storage array contributes a portion of the SSD storage to storage pools of a distributed elastic storage system,
